Question

A bus starts from rest and moves with a uniform acceleration of 1m/s^2 for 5mins . calculate the speed acquired and the distance traveled by the bus

Answer 1

Answer:

Here we have,  Initial velocity (u) = 0 m/s  Acceleration (a) = 0.1ms–2  Time (t) = 2 minute = 120 seconds  (a) The speed acquired:  We know that, v = u + at  ⇒ v = 0 + 0.1 × 120 m/s  ⇒ v = 12 m/s Thus, the bus will acquire a speed of 12 m/s after 2 minute with the given acceleration. (b) The distance travelled:  We know that, s = ut + 1/ 2 at2  = 0 × 120 + 1 /2 × 0.1 × (120)2  = 1/ 2 × 0.1 ×14400 m = 720 m  Thus, bus will travel a distance of 720 m in the given time of 2 minute. Read more on Sarthaks.com - https://www.sarthaks.com/10275/bus-starting-from-rest-moves-with-uniform-acceleration-1ms-minutes-find-the-speed-acquired
